Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is designed to prevent birds such as pigeons, goats, crows, and crows from flying to temples, train stations, private verandas, parks, and the like. The present invention relates to improvement of the prevention device.

(Prior Art) The Applicant has noticed that there are small magnetites in the head of the bird, and that various experimental results show that the bird has a large relationship with the earth's magnetic field, and the abnormal magnetic field is locally detected. We have devised a device (Jpn. Application No. 63-42278) that prevents birds from flying to places that are harmful to humans by generating them. This is the earth's magnetic field (about 0.45 to 0.5 gauss in Japan)
A hemispherical magnetic body with a magnetic force that can locally change the position of a pillar with a height of about 10 cm so that it can be easily installed at an appropriate position such as a veranda, a station yard, a park, etc. and effective flight prevention can be obtained. The necessary number is arranged at appropriate intervals on the thread line for tensioning, which is different from the conventional bird's eye protection such as pseudo eyeballs etc. Since it acts on the body, it does not get used to it, and it is fully effective.

(Problems to be solved by the invention) As described above, the flying prevention device for preventing the flying of birds by generating the fluctuating magnetic field and the disturbance of the magnetic field is fixedly attached to each place (veranda, park, shrine, etc.). Although it has been used successfully and has brought about a great gospel in bird pollution in recent years, there is a long-awaited need for devices and instruments that have a better bird-prevention effect against the current damage. There is.

The present invention has been made in view of the above points, and it is possible to install a magnet body that effectively generates a fluctuating magnetic field to improve the bird-prevention action as compared with existing fly-in prevention devices. An object of the present invention is to provide a bird flying prevention device that is easy to install and can be easily attached to any place.

(Means for Solving the Problem) The gist of the present invention for achieving the above-mentioned object is to hang a thread line for tensioning at a predetermined height position with a strut and to provide an appropriate interval to the thread line. In a bird flying prevention device including a magnet body, one of a pair of magnet bodies formed into a substantially hemispherical shape and provided with an insertion hole having a cut surface as an opening has a cut surface side as an N pole and a tip side as a distal end side. S poles, the other end is the S pole, the tip side is the N pole, and the pair of magnets are the S poles when the two poles are the S poles by the locking bodies that project the insertion portions that can be inserted into the insertion holes on both sides. , N poles are formed in a substantially spherical shape, and a guide groove for a tension wire is engraved on one side of the locking body so that the spherical magnet can be locked to the tension wire. A bird flying prevention device characterized by the above.

(Operation) As described above, in the bird flying prevention device of the present invention, the insertion portion on the guide groove side is placed in the insertion hole of one hemispherical magnet body with the thread line for tensioning passed through the guide groove of the locking body. Then, the other insertion portion of the locking body is fitted into the insertion hole of the other magnet body to form a substantially spherical magnet body that is locked and fixed to the thread line for stretching. In this way, it is sufficient to form a substantially spherical magnet body at appropriate intervals on the thread line for tensioning, and to hang the thread line at a predetermined height on the supporting column. At appropriate intervals on the thread line for tensioning. Each of the substantially spherical magnets arranged has a magnetic pole having an N pole at the upper end and an S pole at the lower end, or a magnetic pole having an S pole at the upper end and an N pole at the lower end. , A rectangular parallelepiped etc.) creates a magnetic field in the space where magnetic force effectively acts in all directions, which is not possible with a rectangular parallelepiped, etc., and because an abnormal fluctuation magnetic field completely different from the earth's magnetic field can be effectively generated at the installation site, Compared to the existing equipment, the effect of preventing flying can be enhanced, and it is possible to sufficiently deal with large damage. Of course, the installation method of this device is very simple, and anyone can easily install it at an appropriate place.
